 # MAUI Templates
 
-## Building / Testing
+For easy building and testing you can use the `build.ps1` script. This script is only for manual use and not part of any pipeline.
 
-Add the local artifacts to the NuGet.config:
+## Functionality
 
-```xml
-<add key="LocalMauiTemplates" value="./artifacts" />
-```
+The script:
+* Deletes the `.tempTemplateOutput` folder which is used for the temporary files used by this script
+* Builds the `src\Templates\src\Microsoft.Maui.Templates.csproj` project
+* Packs the `src\Templates\src\Microsoft.Maui.Templates.csproj` project into a .nupkg file and outputs it to the `.tempTemplateOutput` directory, this directly is excluded from git
+* Uninstalls any previous manual installations of .NET MAUI templates
+* Empties the `~\templateengine` folder
+* Finds and installs the resulting .nupkg artifact in the `.tempTemplateOutput` directory
+* Creates a new .NET MAUI project based on the latest changes in the template
+* Opens the new .NET MAUI project in Visual Studio (or on Mac in Visual Studio Code)
 
-```dotnetcli
-# uninstall, build, and install the templates
-dotnet new uninstall Microsoft.Maui.Templates.net8
-dotnet pack Microsoft.Maui.sln
-dotnet new install artifacts\packages\Release\Shipping\Microsoft.Maui.Templates.*.nupkg
+## Parameters
 
-# then just in the maui folder, so you get a NuGet.config
-mkdir myproject
-cd myproject
-dotnet new maui
-```
+The script defines a coupe of parameters you can use. All have default values, so you only have to set them whenever you want to deviate from the default behavior.
+
+The parameters are as follows:
+
+* `projectType`: Specifies the type of .NET project to create (default is `maui`).
+* `templateVersion`: Specifies the version number to use for the template pack build (default is `13.3.7`, needs to be a valid major, minor, patch version number, for example 1.2.3).
+* `templatesProjectPath`: Specifies the path to the template project to build (default is `src\Microsoft.Maui.Templates.csproj`).
+* `startVsAfterBuild`: Specifies whether to start Visual Studio (Code) after creating the new project with the latest template changes (default is `true`).
+
+### Example usage with parameters
+
+Find sample usages of the different parameters below, of course these can be mixed and matched as needed.
+
+* Instead of a default .NET MAUI app, use the Blazor Hybrid template: `.\build.ps1 -projectType maui-blazor`
+* Set a custom version number for the template: `.\build.ps1 -templateVersion 1.2.3`
+* Build another template project: `.\build.ps1 -templatesProjectPath src\Microsoft.Maui.Templates-new.csproj`
+* Don't start VS after creating the new project using the latest template changes: `.\build.ps1 -startVsAfterBuild $false`
